Pellet Information

POLYETHYLENE PELLET INFORMATION:

HDPE resins are manufactured as odorless white pellets or granules.  The pellets are used in industrial fabrication processes such as blow molding, injection molding, and extrusion. The range of plastic containers and other products made with HDPE resins is vast. Examples are liquid food bottles (e.g. milk containers); containers for household cleaning products, pharmaceuticals, and personal-care products; industrial drums and pails; fuel tanks; truck bed-liners; housewares; toys; sporting goods; and pipe and conduit. Major film applications for HDPE are T-shirt sacks and plastic grocery sacks.  Vapor from the heated resin may cause mild discomfort and redness of the eyes or respiratory irritation. Prolonged skin contact is essentially nonirritating. These resins are often processed as molten polymer at elevated temperatures.  Contact with the heated resin may cause burns.  For further details, see Health Information.  Because HDPE resins are used extensively in food packaging and other consumer products, consumer contact is likely. Resins used for food contact are in compliance with applicable U.S. Food and Drug Administration (FDA) regulations and European Union (EU)

Eye and Skin Contact – Eye contact with HDPE resins or dust may cause irritation or corneal injury due to mechanical action (scratching). Vapor from the heated resin may cause mild discomfort and redness of the eyes. Prolonged skin contact is essentially nonirritating. These materials are often processed as molten polymers at elevated temperatures and skin contact with the heated material may cause burns.

Inhalation – No adverse effects are anticipated from a single exposure to dust. Vapors or fumes released during thermal processing may cause respiratory irritation.

Ingestion – These materials have very low toxicity if swallowed. However, the granules may represent a choking hazard.

 

POLYPROPYLENE PELLETS:

Also known as PP resin, Polypropylene resin is a synthetic polymer that can be used to create a wide range of products. This polymer is made from a combination of propylene and other materials that in decades past were considered to be waste material. Since the development of polypropylene resin during the middle of the 20th century, the resin has been used to make such diverse products as upholstery for car seats and home furnishings, loudspeaker covers, and a number of plastic items for use around the home as well as in the laboratory.There are several benefits to polypropylene resin that set it apart from other plastics and plastic blends.

Uses

A common application for polypropylene is as bi-axially oriented polypropylene (BOPP). These BOPP sheets are used to make a wide variety of materials including clear bags. When polypropylene is bi-axially oriented, it becomes crystal clear and serves as an excellent packaging material for artistic and retail products.

Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats to be used at home. Polypropylene is widely used in ropes, distinctive because they are light enough to float in water For equal mass and construction, polypropylene rope is similar in strength to polyester rope. Polypropylene costs less than most other synthetic fibers. Polypropylene is also used as an alternative to polyvinyl chloride (PVC) as insulation for electrical cables for LSZH cable in low-ventilation environments, primarily tunnels. This is because it emits less smoke and no toxic halogens, which may lead to production of acid in high-temperature conditions.Polypropylene is also used in particular roofing membranes as the waterproofing top layer of single-ply systems as opposed to modified-bit systems.

Polypropylene is most commonly used for plastic moldings, wherein it is injected into a mold while molten, forming complex shapes at relatively low cost and high volume; examples include bottle tops, bottles, and fittings.

It can also be produced in sheet form, widely used for the production of stationery folders, packaging, and storage boxes. The wide color range, durability, low cost, and resistance to dirt make it ideal as a protective cover for papers and other materials. It is used in Rubik's cube stickers because of these characteristics.
